FOXING FO'R RUBBER Boo-rs OR SHOES.

SPECIFICATION forming part of Letters Patent No. 722,823, dated March1'7, 1903.

Application filed January 31, 1902.

To all whom it may concern:

Be it known that I, HENRY J. DOUGHTY, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Foxing for RubberBoots or Shoes, of which the following is a specification.

In the manufacture of rubber boots and shoes strips are used tostrengthen the joint between the uppers and the sole and also at otherparts of the boot or shoe to ornament. or strengthen the same. Thesefoxing-strips were heretofore formed in sheets of rubbercoated textilematerial and required to be out into strips.

I have prepared an improved forcing-strip. of pure-rubber compound, theinner face of which adheres to the boot or shoe, while the outer surfaceenlarges from the edge where it unites with the vamp or the quartersgradually outward to the point where the foxing reaches the sole andthen turns inward to the end of the foxing. By this construction thefoxing is materially strengthened at the intersection of the vamp andquarters with the sole of the boot or shoe.

The object of this invention is to facilitate the use and handling ofrubber foxing; and to this end the invention consists in forming thestrips of foxing in the desired formsof' rubber without the use oftextile material and connect theseveral strips to each otherv by a thinknife-edge, as will be more fully set forth hereinafter. V

Figure 1 is an end view of a calender for rolling my improved sheet offoxing-strips. Fig. 2 is a side view, on an enlarged scale, of parts ofthe two rolls of the calender, showing the manner of forming thefoxing-strips with the thin connecting edges. Fig. dis a perspectiveview of a sheet of foxing, indicatin g in broken lines the manner ofseparating the strips from the sheet by tearing. Fig. 4; is aperspective view of'one of the torn-oi foxing-strips.

In the drawings, A indicates the frame of the calender, and a the smoothroller, journaled in bearings supported on the frame of the calender.The gear a is secured to the shaft of the roller 6 and is operated bythe pinion a secured to a counter-shaft, to which the driving-pulley ais secured. The roller 1) is supported in sliding bearings.

Part of Serial No. 92,068. (No specimens.)

' the roller 1) has the circumferential grooves and beveled surfacescorresponding with the different forms of foxing-strips required. Thegrooves and beveled surfaces are separated bythe knife-edges 19 12 whichwhen the ends of the roller b are in contact with the roller Ct nearlytouch the roller a, as is clearly shown in Fig.2. b b are the centralenlargements of the foxing. The roller 1) is forced against the roller0, by the screw 0, and when the sheet of rubber is rolled the differentstrips forming the sheet adhere to each other by the thin film of rubberconnecting the strips.

In the preferred form a sheet of foxing consists of a sufficient numberof strips of the different forms required to trim one or more rubbershoes. The sheet is not liable to injury in handling, and when the bootor shoe trimmer requires a strip of foxing the same may be readily tornfrom the sheet.

In arranging for the manufacture of the foxing I form the roller b sothat the forcingstrips successively required will be always at one ofthe two edges of the sheet and may be torn ofi successively as they arerequired.

In molding a rubber boot or shoe the foxing made after my inventionsecures a more perfect line in the mold and prevents the sticking of theshoe to the mold.

- Having thus described my invention, I

claim as'new'a'nd desire to secure by Letters Patent- 1. The new articleof manufacture consisting of a sheet composed entirely ofunvulcanized-rubber compound and formed into strips of foxing connectedby a film of the compound, whereby the strips may be separated bytearing, as described.

2. Foxing-strips composed entirely of vulcanizable compound having afilm on either end and a central enlargement, as described.

3. Asheet formed entirely of unvulcanizedrubber compound having a seriesof the different kinds of foxing required to trim rubber shoes connectedtogether by films of the compound, as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HENRY J. DOUGH'IY.
